# ICPP - Running C++ in anywhere like a script
**Interpreting C++, executing the source and executable like a script.**
* Writing powerful script using C++ just as easy as Python;
* Writing hot-loading C++ script code in running process;
* Based on [Unicorn Engine](https://github.com/unicorn-engine/unicorn.git) qemu virtual cpu and [Clang/LLVM](https://github.com/llvm/llvm-project.git) C++ compiler;
* Integrated internally with [Standard C++23](https://en.cppreference.com/w/cpp/23) and [Boost](https://github.com/boostorg/boost.git) libraries;
* To reuse the existing C/C++ library as an icpp module extension is extremely simple.Copyright (c) vpand.com 2024.

**Using ICPP to write C++ code just as a script.** Write and then run directly, no creating project, no configuring build, no compiling and linking...No matter if you're a beginner or an expert with C++, ICPP is suitable for you. With ICPP, you can focus on:
* Writing **snippet code** to study any of the newest C++ features;
* Writing **glue script** to do some tasks;
* Writing **test code** before applying to the formal project;
* Writing **sample code** to study some new third C/C++ libraries;
* Making native plugin development scriptable, i.e., **writing plugin using C++ dynamically**.
* Tracing, profiling, performance optimizing;
* And so on...**ICPP, make programming all in one.**
## How it works
### Interpreter
Local interpreter mode lets you run C++ directly in your local system.
```mermaid
graph LR
A(C++ Source) -- Clang --> B(Object)
B -- Loader --> C(ICPP Interpreter)
A(C++ Source) -- Source.io --> H(IObject)
H(IObject) -- Parser --> C
E(Executable) -- Loader --> C
C -- Unicorn --> D(Output)
C -- Tracer --> F(Traces)
C -- Profiler --> G(Profiles)
```### Hot-loading
Remote interpreter mode lets you run C++ remotely in a different process or system which loads the icpp-gadget library. This mode allows you to run C++ code dynamically in a running local process or a remote system like Android/iOS.
```mermaid
graph LR
A(C++ Source) -- ICPP --> B(IObject)
B -- IOPAD --> C(ICPP Gadget)
C -- Interpreter --> D(Run in Process)
C -- Extension --> E(Hooking/Tracing)
C -- Extension --> F(Testing)
```## Usage
### Summarization
* **icpp**: a local C++ source compiler, interpreter and REPL used to interpret C++ directly;
* **imod**: an icpp module package manager tool used to install, uninstall and show the third-party modules;
* **iopad**: a local C++ source compiler driver, object launch pad and REPL for the remote icpp-gadget;
* **icpp-gadget**: a remote memory resident daemon which may run inside an Android/iOS process, waiting for iopad to send the interpretable object to execute.
* **icpp-server**: a remote icpp-gadget server daemon, waiting for iopad to send the interpretable object to execute.### VSCode
Within an IDE frontend should be easier and more convenient to use the icpp package, you can download it at the [icpp-vscode](https://github.com/vpand/icpp-vscode/releases) release page or search "icpp" in vscode extension market.### ICPP CLI

To build your own version of icpp, make sure all of the **prerequisites** are in your system PATH environment:
* **CMake** (version >= 3.20);
* **Python** (Windows), Python3 (macOS/Linux);
* **Ninja** (Windows), **Make** (macOS/Linux);
* Visual Studio with **LLVM Toolchain** (Windows);### Clone
```sh
# clone icpp
git clone --depth=1 https://github.com/vpand/icpp.git
cd icpp
# clone llvm, unicorn engine, boost, etc.
git submodule update --init --recursive --depth=1
mkdir build
cd build
```### CMake
#### Windows X86_64
```sh
# NOTE:
# all the following steps must be done in "x64 Native Tools Command Prompt for VS"
# or
# run VS_ROOT/.../VC/Auxiliary/Build/vcvarsall.bat to initialize for 'x64'
vcvarsall x64
# we use clang-cl as our compiler, to make it working, you should:
# have installed the Visual Studio with LLVM Toolchain support.
cmake -G Ninja -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_BUILD_TYPE=Release ..
```#### Windows ARM64
```sh
# NOTE:
# all the following steps must be done in "ARM64 Native Tools Command Prompt for VS"
# or
# run VS_ROOT/.../VC/Auxiliary/Build/vcvarsall.bat to initialize for 'arm64'
vcvarsall arm64
# we use clang-cl as our compiler, to make it working, you should:
# have installed the Visual Studio with LLVM Toolchain support.
#
# Because of the cmake script of boost and unicorn has kind of hardcode snippet for
# some paths, like the path of lib.exe, assembler search directory, so we have some
# extra steps to make this cmake command working:
# 1.copy llvm-lib.exe as lib.exe in LLVM_ROOT/bin;
# 2.copy VC_ROOT/bin/armasm64.exe to LLVM_ROOT/bin/armasm64.exe.exe;
# 3.build cmake/boost/armasm64 and copy it to LLVM_ROOT/bin/armasm64.exe;
#
cmake -G Ninja -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_MT=llvm-mt -DCMAKE_ASM_MASM_COMPILE_OBJECT=armasm64 -DCMAKE_BUILD_TYPE=Release ..
```#### Linux AArch64/X86_64
```sh
# create the clang to be customized building scripts
cmake -B clangconf -DCMAKE_BUILD_TYPE=Release ../cmake/clangconf
# build our clang compiler with itself's libc++ support
cmake --build clangconf -- clang runtimes -j8
# use the clang that we built before as our compiler
cmake -DCMAKE_C_COMPILER=$PWD/llvm/bin/clang -DCMAKE_CXX_COMPILER=$PWD/llvm/bin/clang -DCMAKE_BUILD_TYPE=Release ..
```#### macOS ARM64/X86_64
```sh
# if your system default clang doesn't support C++20 before the version of macOS 14,
# you should compile your own clang and apply it like on Linux.
#
# This is a very complicated process. So I strongly recommend that you update your
# macOS and Xcode to the latest version to have the C++20 support to simplify the building.
cmake -DCMAKE_BUILD_TYPE=Release ..
```### Make
```sh
# build the protoc compiler
cmake --build . -- protoc -j8
# build all the icpp components
cmake --build . -- icpp icppcli imod iopad icpp-gadget icpp-server -j8
```### Pre-Run
The newly built naked icpp needs the include/lib related stuff to work. The simplest way to run your own version is to replace the binary in the official release package. If you want to run it in the build directory, you need to construct the directory layout just like in the release package. e.g:
```sh
build:
---include
------header-related
---src
------icpp
---module
------std.compat.cppm
------std.cppm
---lib
------lib-related
